| Popis: | International audience; In the frame of the CleanSky2 project AFC4TR (GrantAgreement 886718), detailed studies are made on the use of Active Flow Control (AFC) on the Next Generation Civil Tilt Rotor (NGCTR) aircraft. This is fully in line with the mission of the Clean Aviation Joint Undertaking to develop disruptive new aircraft technologies to support the European Green Deal, and climate neutrality by 2050. The NGCTR is a novel aircraft concept combining the capabilities of vertical take-off and landing of a helicopter with the range and the speed of a fixed wing aircraft. Active Flow Control on the NGCTR is studied using so called Zero Net Mass Flux (ZNMF) devices. The application of these devices have been worldwide intensively investigated due to its effectiveness and simple implementation. These actuators do not require a piping for pressurized air source, yet create non-zero-net momentum flux via periodic suction and ejection of fluid through an orifice. Although the efficiency of ZNMF actuators for relatively simple airfoils in 2D have been pointed out by previous studies, the benefits of integrating ZNMF into a whole aircraft for real and unsteady flight condition is still an open question. More recently, we studied two-dimensional active control using different strategies of steady blowing, transient blowing and blowing-suction method similar as piezo-actuators embedded inside the flap of a high-lift system. The AFC was coupled with a morphing flap using the cambering approach. The coupling could re-attach the boundary layer, enhance the pressure distribution over both the flap and the wing system and decrease the width of the wake. In this study, we expand our previous studies by investigating the benefits of integrating ZNMF into a whole tilt rotor aircraft for real and unsteady flight condition. |
